It remains to be seen what impact the recent Occupy Wall Street protests will have on systemic corruption and economic inequality. But protesters at least got something out of it Tuesday night: Free Jeff Mangum gig! The Neutral Milk Hotel frontman stopped by the protest to perform a half-hour set, playing classics like "Oh Comely" and "Holland 1945" as well as a cover of Minutemen's "Themselves." You can watch footage of the performance below. [Via Pitchfork]
